I have the usual intense constant pain in stomach/pelvic area and also a pressure feeling in my bum while on my period which is horrible.......when bleeding has stopped I am left with terrible back ache that can also go down my hips and also still the pressure feeling in back end. I can also get sharp pains in stomach but this is not constantly and not as bad as when I first come on.

Yes I do. I haven't had a period in over six months and still have constant pelvic pain and other endo symptoms. Sorry you are dealing with it too. I find physical therapy and pain management have helped me learn to live with it.

Yeah i experience this too !!
